The invention provides a fire-fighting spray head assembly, a fire-fighting spray pipe and a fire-fighting unmanned aerial vehicle, and relates to the technical field of fire fighting. The fire sprinkler assembly comprises a nozzle body and a sheet type flow stabilizing piece. A pipe cavity is formed in the nozzle body; the sheet type flow stabilizing piece is arranged in the pipe cavity, the sheet type flow stabilizing piece abuts against the cavity wall of the pipe cavity, and independent fluid channels are formed between the sheet type flow stabilizing piece and the cavity wall. By applying the fire-fighting spray head assembly provided by the invention, the fire extinguishing agent can be subjected to steady flow adjustment, the jet kinetic energy loss caused by vortex is reduced, the jet flow disturbance is reduced, the flow direction speed of the fire extinguishing agent during jet is ensured, the jet stability of the fire extinguishing agent is improved, and the jet distance is effectively ensured.

    本发明提供一种消防喷头组件、消防喷管及消防无人机,涉及消防技术领域。消防喷头组件包括喷嘴本体及片式稳流件。喷嘴本体内形成管腔;片式稳流件设置于管腔,片式稳流件抵接于管腔的腔壁,片式稳流件与腔壁之间形成彼此独立的流体通道。应用本发明提供的消防喷头组件,可以对灭火剂进行稳流调整,减小因涡流导致的喷射动能损失,减小射流扰动,保证灭火剂喷射时的流向速度,提高灭火剂的喷射稳定性,有效保证喷射距离。
